Application filed. February 19, 1917. serial No. 149,386. 1

To all Whom it may concern Be it known that I, ARTHUR H. Roenns,'a citiren of the United States of America,'residing in the city of Springfield, county of Hampden, and State of Massachusetts, have invented certain new and useful Improvements in Rubber Stamps of the Band Type, of which the following is a specification.

This invention relates to improvements in dating stamps of the type in which continuous type bands are used bearing the year, month, and day of the month type characters.

Broadly, the invention comprises an inclosing casing within which is mounted a 'slidable frame with means for locking the same in different positions of adjustment. An object of the in ention is to provide means for automatically alining the type so that when the stamp is used. the printing type on each band will correctly stand in Heretofore, in this class of stamps, unless great .care is taken to aline the type on the bands they will not be arranged correctly when the printing is effected. A further object of the invention is to provide means for individually rotating the bands for bringing the printing type into alinement when the slidable frame is moved into its printing position. Afurther object is to provide means for cushioning the bands which bear the type. Other objects of the invention will fully appear in the body of Fig' 1, illustrating the movable type band carrying frame, the guiding devices for the frame at the top and bottom portions of the casing and the inclined and curved edges of the opening through which the type on th bands projects for a'lining the same;

Fig. .4 is a vertical sectional view :on the .line 4% of Fig.- 2, showing thethreaded adjustment and stop pin in the cap for guiding and adjusting the movable frame, also the construction of the shafts, whereby the individualtype bands are turnedv when desired, and the plate or bridge piece at the lower end of the movable frame for guiding the'bands;-m t

Fig. 5 is a sectional view on the line .5- -5 of F ig. 4, illustrating in detail the constructlon of the spring and adjustable stop. pin for normally retaining the movableframe in printing position, the full line position v shown being that in which the movable :fra me can be ralsed for ad ustlng the type and in exaggerated .dotted'lines the position of the mo able frame in the printing position;

Fig. 6 is an end and side elevational view of'one of the sprocket wheels over which "the type bands pass; 7 v v V Fig. '7 is a sectional view of the tvpe-band showing the cushion recesses which receive the teeth 'of the sprocket wheels. and also the em edded strengthening thread; r

Fig. .8 illustrates the removable name plate; o

Fig. 9 is a perspective detail view *of a section of the type band, showing the strengtheningthread in dotted lines; and 1 Fig. 10 is-a detail view of the upper end of the movable type carrying frame, the adjus'ting and stop screw pin in the cover being shown intheyposition to? lock the frame against upward movement, I

Referring to the drawings in detail, the incl'osing casing is indicated at 1, and is formed wthan intermediate neck portion .2

and enlarged portions 3 and 4. The upper end is preferably made circular and s formed with a thread for receiving theper-v forated cap '5. Formed in the center-of this cap is a-threaded opening in which is located the threaded adjusting and stop pin. A slidable frame is mounted in the inclosing casing land is formed with the side plates :7 and 8 that extend substantially the entire length of the interior of the inclosing Gasing. This frame supports the three endless rubber type .ca-rrying 'bandsjt). 10 and 11 (see F ig; 4) which is formed with the type for-printing the yearymonth and day, re-

spectively, the day band 9 being the longest since there are more numerals in the month thanin either the year or month bands; If desired this band may. be made shorter and the numbers corresponding to the days of "the month-put on more than one band.

In order to rotate these band-ssprocket Wheels 11!, 1'2, andi13 are provided which did type carrying bands pass.

plate-28 near the opening 31 are clownare rotatably mounted in the frame; the sprocket wheels 11 and 12 are mounted for independent rotation with relation to each other on the small pin or shaft 1 lwhich consists of a round pin that extends throu 'h openings in the sides 7 and 8 of the movable frame and terminates within the hubs and 16 of the band operating buttons 17 and 18. The hubs of these buttons are rectangular for engaging similar shaped recesses 19 in the sprocket wheels 11 and 12. The teeth 20 of these sprocket wheels enter recesses 21 in the type bands, whereby not only a rotative effect is transmitted to the bands but a cushioning effect where it passes over the bridge at the lower end of the movable frame;

The day of the month band 9 is similarly rotated by means of the sprocket wheel 13 by means of the rectangular or suitablyconstructed shaft 22 which passes therethrough. This shaft passes through openings in the opposite sides of the movable frame and through a rectangular shaped opening in the sprocket wheel 13 over which the type band passes that carries the days of the month numbers. This shaft carries the operating buttons 23 and 24- at its opposite ends for rotating the sprocket wheel 13. In order to form a suitable surface over which the lower portions of each of the type bands pass, a bridge piece 25. having its lower surface curved is provided. This piece is mounted on a detachable plate 26 which is supported in and frictionally secured to the side plates 7 and 8 at their lower ends, as shown in Figs. 3 and 4- by means of the slits therein. as indicated inl ig. 4 at 27. This piece 25 maybe made adjustable, if desired. The opposite ends of the plate 26 engage oppositely located vertically arranged grooves in tne face plate 28 which is secured to the frame 1 at its lower end by means of the screws 29 (see Fig. 3). The plate 28is formed with a large rectangular shaped opening 31 through which the three Secured to the wardly extending plates 32 which are spaced from each other and are formed with the curved shoulders or throat surfaces 33 that are adjacent the space 34 between the plates 32 through which the type of the several type bands project, as clearly shown in Figs. 3 and 4 when in printing position. Above the opening 3-4 the plates are inclined. The curved surfaces are for the purpose of automatically alining the type characters when the same are pushed downward through this opening by means of the operating buttons 23 and 24. The movable type band carrying frame is adapted to be retained in its lowermost position by means of the screw pin 35, the upper end of which is secured to the cap 5 by the threads 36. The lower end of this pin normally engages the bridge piece frame is normally held in the position shown in 5 and 10 by means of the spring 38; the end 39 of which engages the edge 37 and the end 35) enters an opening, in the inclosinp; casing (see Fig. 5). The type carrying frame is held against vertical movement when in this position by means of the pin 35 which engages the bridge piece 37 and the recessed slots e1 when the stamp is used for printing. ll hen the type is to be moved in order to print a different date the operator first moves the shaft 22 out of the recesses 1:1 by grasping the buttons 23 and 2 a. bringing this shaft in alinement with the elongated slot' il in tl e side of the casing, and. at the same time the lower end of the pin 35 is brought ivcr the opening 14 in the frame 37 whereby the type carrying frame, as a whole, can be lifted upward away from the lower opening 3% permitting the several type-bands to be adjustel by means of the buttons 23, 2%, l7 and 18. After the type bands have been adjusted to the correct dates the operator again moves the frame downward carrying the type of the bands through the opening 34 and at the same time the spring 38 moves the shaft 22 into the locking; recesses 41. In order to vertically adjust the type carrying frame the screw 35 is operated to move this frame downward the correct distance so that it will cause the type to project the correct distance beyond the face of the lower printing die 45. The operator then pushes downward on the but tons 23 and 2- thus forcing the type on the three bands through the opening 3t and by reason of the slash-ins; or inclined surfaces 33 fon the plates the type on each of the bands is automzdically alined or pinched into alinement in this opening its he pushes downward on the buttons the spring 38 automatically snaps the shaft 22 back intoiocking engagement with the r cesses 41 and holds the type carrying frame locked in the printing position and the end of the pin 35 engaging: the surface 37 (see Fig. 10). In order to accurately adjust the extent of projection of the type through the opening 3 lthe pin as stated. engages the bridge 3?. The rotation of the pin 35,'therefcre, causes the frame carrving the three rubber bands to be moved relative t the casing 1, it being understood that the type carrying frame is locked against upward movement by means of the spring 38 and pin 35. The printing die 45 cemented to the cushion pad 4-3 in the usual manner. I

From this construction it will be seen that T have provided a device for quickly and automatically alining the type of the three hands by means of the pieces 32 having the inclined and curved surfaces33' adjacent the opening 34:: and. I have. provided means; for accurately adjusting the position .of theltype carrying frame relative lIOC- the; casing 1,. also means for automatically locking'the carrying frame in the. adjusting" position, also, means for cushioning the bands on. the bridge piece over which the bands are passed.v It is to be understood that the stamp can be readily taken apart and new bands substituted when desired. The'shaft 22 can be readily removed by 'unscrewingthe cap-23 andthe bands 10 and 11 can be removed by simply withdrawing the buttons 17 and 18 from theirsproc'ket wheels and the pin 15; this pin permits the sprocket wheels to rotate independent of each other. The buttons 17 and'18 are easilyro'tated by means of the ribsl? and 18". It will be seen that the fixed and spaced curved surfaces 33 afford means fer automatically alining the type on the bands When'the movable frame is moved downward.

Referringto Figs. 7 and'9, 21 designates threads which are embedded in the'rubber of the type printing bands in order t'o'prevent stretching and for strengthening the same against breakage. Theends of this band are suitably secured together, as by sewing. These bands, as shown, are formed with recesses to receive sprocket wheels.

The thickness oftheweb of rubber betweenthe type is substantially equal to the thickness of the threadlike element.
